Written for teenagers but invaluable reading for those coping with them—parents, doctors, and teachers—Blame My Brain, a guide to the biology behind teenage behaviour, is informative, accessible, interactive, and fun. There are self administered “tests,” scientific explanations (including wonderful images of trees to depict brain development), useful advice about emotions, sleep, risk, and harmful behaviours, and guidance about websites and other sources of reliable information. I am a parent of three teenagers, and many of its stories about getting risk in proportion rang bells for me.
